Patented Nov. 24, 1936 UNITED STATES LOOM TEMPLE Ira W. Noyes, Hopedale,Mass, assignor to Draper Corporation, Hopedale, Mass, a corporation ofMaine Application February 24, 1936, Serial No. 65,316 7 Claims.(cries-303) The present invention pertains to loom temples and has moreparticular reference to such temples of the type embodying a threadcutting mechanism.

Temples of the type mentioned commonly include a reciprocably mountedbar carrying at its rearward end a laterally extending head. The templehead, in which a fabric engaging roller is mounted, includes a capdetachably secured to the temple bar, there being a guideway extend--ing through the head for reception of a rocking and sliding cutterblade. In prior constructions, downward rocking movement of the cutterblade is limited by cooperating surfaces formed on the cutter blade andtemple bar at the bottom of the guideway, while other cooperatingsurfaces on the cutter blade and the exterior of the bar limit rearwardsliding movement of the cutter blade.

The prior construction as just described has proven unsatisfactory intwo respects. First, since the roll pin on which the fabric grippingroller is mounted extends across the guideway, a wearing of theaforesaid surface at the bottom of the guideway permits the cutter bladeto drop down into contact with the roll pin and wear the latter in two.Second, a wearing of the aforesaid exterior surfaces of the temple barpermits the thread cutter blade to project too far rearwardly out of thetemple and to thus come into contact with the reed. Temples which becomeworn as mentioned can be satisfactorily repaired only by replacing theworn temple bar with a new one, the temple bar being a comparativelylarge and expensive part.

I propose to correct the aforementioned defects by providing, in atemple of the class described, cooperating wearing surfaces whichsupport the thread cutter blade out of contact with the roll pin andwhich are formed on parts which are relatively cheaply and easilyreplaced. I further propose to provide, in such temples, coopratingsurfaces for limiting rearward movement of the cutter blade, whichsurfaces are also formed on such replaceable parts.

4,5v In accordance with the invention, I have provided in a loom templehaving a temple bar, head, detachable cap, guideway, and thread cutterblade 'as above described, a lug which projects into the guideway andwhich has a surface cooperating 50 with a surface on the cutter blade tosupport the latter out of Contact with the roll in; The lug may furtherbe provided with another surfaceengaging the cutter blade to limitrearward movement of the latter. The lug is carried by the 65;detachable temple cap, wherefore when the lug becomes worn the damagecan be repaired simply by replacing the cap with a new cap having a newlug therein or, if the lug is detachably. secured to the cap as hereindisclosed, the damage can be repaired by merely replacing the worn lugwith a 5 new one. In either event, the replacing of the cap or the lugis much simpler and much less expensive than replacing the larger partherein called the temple bar.

The preferred embodiment of the invention is 10 illustrated on theaccompanying drawing, of which:

Fig. l is a plan view of the temple, with the cap partly broken away;

. Fig. 2 is a view in elevation of the rear face 15 of the temple;

Fig. 3 is a view in elevation of the outside face of the temple with thecap partly broken away and appearing in section; and 1 Fig. 4 is a viewsimilar to Fig. 3 but showing 20 the thread cutter blade in a differentposition.

The temple shown on the drawing includes a housing I which is adapted tobe fixed to a loom frame (not shown) in the usual manner. A bar 2 isreciprocably mounted in the housing I, the 25 bar extending generallylongitudinally of the cloth C being woven. The temple bar has at itsrearward end a laterally extending head which includes a pod 3,depending heel 4 and other parts, formed integrally with the partdesignated 30 generally as the temple bar.

The temple head also includes a cap 5 which is detachably secured to thebar as by means of a screw 6. The temple head has a guideway 1 extendingtherethrough from front to rear. guideway is generally parallel to thebar 2 and is formed partly in the bar portion and partly in the capportion of the temple head. A cutter blade 8 is mounted in the guidewayfor rocking and sliding movements, the particular cutter 40 blade shownbeing constructed, and operating, as is more fully disclosed in patentto F. E. Douglas, No. 1,919,146, granted July 18, 1933. The temple headalso includes a roll pin 9 which is carried by the end wall It of thecap and extends across the guideway l, on which roll pin the fabricengaging roller I I is rotatably mounted.

The temple as thus far described is of usual construction. The operationof the thread cutter blade is also conventional. however, that a springI2 normally holds the cutter blade rearwardly with the rearmost endthereof well up in the guideway, and that when the cutter blade is givenits operative stroke it first rocks about a horizontal axis, depressingits rear- 55 The 35- It may be here noted,

most end, and then slides bodily forwardly. After its operative movementthe cutter blade is returned rearwardly by the spring if. It will beapparent that, in the absence of means preventing such occurrence, awearing of the surfaces which limit downward rocking movement of thecutter blade would permit the latter to engage the roll pin, while awearing of the surfaces which limit the rearward sliding movement of thecutter blade would permit the latter to project too far rearwardly outof the temple.

In prior constructions, the aforementioned wearing surfaces were formedon the thread cutter blade and on portions of the temple head which wereintegral with the bar. Thus, in order to repair such worn temples it hasbeen necessary to replace at considerable expensenot only the cutterblade but also the entire temple bar. The present invention provides apart, in the form of a lug, having wearing surfaces for the purposementioned, which part can be replaced at substantially less expense thanreplacement of the temple bar.

The lug I3 shown on the drawing projects into the guideway I and isattached to and carried by the cap 5, preferably by the end wall lthereof. The lug has a horizontal surface [4 which cooperates with asurface on the thread cutter blade to limit downward rocking movement ofthe cutter blade and thereby support the same out of contact with theroll pin 9. Since the cutter blade 8 is of conventional form, with thesurface 15 above the roll pin, the surface I4 is formed on the top ofthe lug above the roll pin. It will benoted that with this constructiona Wearing of the cutter blade alone would not permit the blade to comein contact with the roll pin.

The lug l3, and the thread cutter blade may also be provided withcooperating surfaces limiting rearward sliding movement of the cutterblade.

The lug shown on the drawing is provided with of the cutter blade.

a vertical surface l6 forwardly of the roll pin which surface cooperateswith the vertical surface l'l normally provided on the thread cutterblade, the surfaces limiting rearward movement It will be noted that thelug l3, including its surfaces I4 and I6 is entirely within theguideway, it being within that portion of the guideway which is formedin the temple cap.

The lug I3 is carried by the end wall ll] of the cap and is preferablydetachably secured thereto. The means for securing the lug to the capmay include the roll pin 9. In the present embodiment, the roll pin isthreaded as shown at l8 and the threads thereof engage in a threadedhole in the lug, the roll pin passing through the lug.

Thus, in this particular embodiment the lug may be replaced with a newone merely upon the removal of the roll pin, but even a replacement ofthe casting, of which the cap is in the main comprised, together withthe lug carried thereby, is simpler and substantially less expensivethan replacing the temple bar.
